Vision for Nirvana: Centuries of safe, secure, competitive energy supplies that meet community expectations for net outcomesTo reach the vision• Potential risks to social, natural and economic environments are
reduced to as low as reasonably practical (ALARP); and meet community expectations for net outcomes BEFORE IT IS PERSONAL – before approval sought for land access;
• Affected people and enterprises get timely information describing risks and rewards to enable informed opinions;
• Convene roundtables to deliver roadmaps for projects to inform: the PUBLIC, GOVERNMENTS, INVESTORS, AND REGULATORS and in doing so – enable/attract welcomed oil and gas projects.

• South Australia’s Petroleum and Geothermal Energy Act 2000 defines the environment as: land, air, water, soil; plants & animals; social, cultural & heritage features; visual amenity; economic & other land uses.
• Activities cannot start without an approved SEO in place.
• SEO’s set standards for outcomes from operations
• SEOs are objective-based, transparent drivers for risk management and the protection of environments.
• ‘Owner of land’ means all people and enterprises potentially directly affected by activities, entitling them to notices of entry, the right to dispute entry (in court) and compensation.
~ 14,000 notices of entry for operations issued – without a single person or enterprise taking up their rights to take the matter to Court
Aspiring to Attain Regulatory Nirvana via Statements of Environmental Objectives (SEOs)

“Recommendation –Establish lead agencies”“South Australia is widely seen as a model for other jurisdictions to emulate”.
“With appropriate governance, experience in South Australia suggests that such an agency can achieve an appropriate balance between enforcing legislative provisions and expediting approvals”.
Productivity Commission concluded:One‐Stop‐Shops are the most efficient regulatory approach when well managed without ‘CAPTURE’
23
Key Conclusions1. Huge potential in unconventional
reservoirs in the Cooper. ~$3.5 blninvestment 2014‐19.
2. Huge potential offshore in the Bight Basin. ~$2.3 Bln investment to 2020
3. Trustworthy regulation / regulators4. The Roundtable for Oil & Gas
Projects will continue to expedite fit‐for‐purpose outcomes to benefit all South Australians 24

• The highest priority defined by the Roundtable for Unconventional Gas is the appropriate recognition of the life‐cycle for finding, appraising, developing and producing resources. Fit‐for‐purpose licenses terms are the most direct way to recognize this life cycle. This is equally relevant to all mineral and energy resource sectors. The Subject Area Arrangement: Avoids 18 ‐24 months delay in exploration/discoveries after: intermittent
relinquishments; call for bids; bids; negotiation of land access agreements; and grant of successively smaller PELs;
Accelerates investment at contestable levels through renewal terms in ways not achieved with PELs;
Delivers investment, jobs, production and royalties, sooner ‐ clearly in the interest of the People of South Australia;
Industry as a whole has greater investment efficiency; Attains very competitive levels of investment without the perverse outcome
of ‘winner’s curse’ bidding;
Key Matters Considered in Decision-Making for the Regulation of PRLs
35
The Subject Area Arrangement (continued): Based on DSD’s mapping of the proven oil play trend ‐ 21 companies in JVs under
10 Operators may opt into Subject Area Agreements (e.g. cross‐section of industry will benefit, including service companies who will get more extensive contracts;.
Nurtures small enterprises to become medium to large in size enterprises; Overcome a looming issue: Ever‐smaller licences attracting circa $20 million bids
(400 sq km 3D + 4 exploration wells) stretch the financial competence of ASX IPOs – and financial competence is a requirement for compliant licence‐holders;
Seeks secure investment at a time the State needs stronger investment; Farm‐outs and sales are expected to further accelerate investment than is likely
to be attracted through success, intermittent work program bids; A company approached Government with a proprietary request to progress
applications for PRLs; Undertook targeted consultation with a cross‐section of key Operators, at least
one non‐Operator and service companies active in the Cooper‐Eromanga basins; The clear majority of enterprises considered the concept of PRLs for oil as a
significant (even visionary) step worth taking; With regret, there little chance that all regulatory decision will please all
stakeholders, always; 36
Patchawarra Formation Overpressure
Patchawarra Formation pressure gradient data derived from DSTs and other data sources. Water pressure gradient is 0.43 psi/ft. Gradients exceeding ~0.45 psi/ft are indicative of overpressured gas. Overpressured gas in the Patchawarra Formation occurs at depths exceeding ~9500’ (~2900m).

Recap Working Groups #2 - Supply hubs, roads, rail and airstrips, Cooper-Eromanga basins• Have mapped existing supply options (road, rail, air, ship); • Used Roadmap details to inform probabalistic dimensions,
weights and timing for transport scenarios – in turn enabling optimisation modelling for road, rail and air for minimum 6,000 pj unconventional gas ex-Cooper Basin to supply a15 year gas contract. Also accounting for oil
• Special facility licences (SFLs) enable additional depots, airstrips and petroleum handling facilities
• DPTI has estimated requirements to seal the Strzelecki Track as part of SA’s Integrated Transport and Land Use Plan. Looking at intra-basin requirements, too
• Building economic models to elucidate public vs private benefit in context of Infrastructure Australia criteria for Federal funding. 44
Leading operators have met / are planning to pool water use forecasts for Cooper-Eromanga (SA-Qld) basin-wide modelling of water supply: demand balance, to deduce cost- and water-saving options.
This is a first, fundamental step towards life-cycle water-use planning – will inevitably foster environmental sustainability, project economics, transparency/trust, and business opportunities.

SEO objectives include:
• Owners of landmeans all persons and enterprises potentially directly affected by regulated activities,
• NoEsmust provide timely information to enable potentially affected people and enterprises to reach informed views regarding impacts on their interests.
• Owners of landmust be given NoEs at least 21 days in advance of the start of any activities – and have 14 days to lodge objections
• All potentially directly affected people and enterprises have rights to object to the approval of land access for regulated activities, and all such objections are a show‐stopper until objections are resolved. 58
Petroleum and Geothermal Energy Act 2000 Regulatory Framework in South Australia
Notices of Entry (NoEs)
• These Owner of Land rights are sustained without support for vexatious objections. Owners of land are due compensation from relevant PGE Act licence holders for reasonable costs of assessing NoEs (including the cost of legal advice) and for any loss or deprivation that might result from activities regulated pursuant to the PGE Act.
• The dispute resolution process for objections to NoEsstarts with engagement between the concerned
stakeholder and the relevant PGE Act Licence holder;can escalate to mediation stewarded by the Minister;

HAZARDOUS EVENTS POTENTIAL CONSEQUENCES MITIGATION MEASURES
Access & pad construction, vehicle & people movement.
Intrusion or physical damage to areas of Aboriginal heritage significance.
Scouting for such sites to be undertaken ahead of activity.
Crossflow from hydrocarbon zones or lesser quality aquifers.
Contamination of aquifers. Pollute water source of other users
Identified aquifers isolated behind casing.
Drilling through fresh water aquifers.
Use of non-toxic muds.
Fraccing into adjacent and overlying aquifers
Non-toxic frac fluid. Monitor frac through micro seismic and control pump pressures accordingly

Fracture half length and complexity is controlled by:• Frac fluid viscosity (gel vs
“slickwater”)• Pump rate• Pump pressure• Proppant “mesh” size• In situ stresses• Existing natural fractures• Natural frac barriers (ductile
rocks that don’t break easily)• Rock brittleness

What is hydraulic fracturing ?
“..is a technique in which a mixture of mainly water mixed with sand (99.5% vol.) and chemicals (0.5% vol.) is injected at high pressure into a well to create small fractures (typically less than 1‐2 mm), along which fluids such as gas and oil may migrate to the well.”
720 wells in the South Australian Cooper Basin have been fracture stimulated without Harm to social, natural or economic environments

Otway Basin - History
• Exploration commenced in 1866 in the South East with a well drilled near Salt Creek
• First flow at Kalangadoo-1 in 1965 and Caroline-1 in 1966 – both CO2
• First commercial flow of hydrocarbons in 1987 at Katnook-1
• Katnook Plant built and commissioned in 1991 – now mothballed
• Oil recovered from Sawpit-1 in 1992, flowed from Wynn-1 in 1994 – neither well commercial
